Yii2 is the latest version of the Yii PHP framework (Yii is a high-performance component-based PHP framework), version 2.0.19 was released on May 21, 2019.

Almost any web application of any usefulness requires some form of user registration. Yii provides a couple of ways to approach user registration, both relatively straightforward. This is one of the things I like about using Yii over vanilla PHP—in moments, I can have a fully featured web application framework ready to build cool stuff on.
